I just got my TT two months ago and this is my first scan with my new VagCom Cable (Thanks Alpha-bid). If anyone has any insight on any of my issues, I'd love the advice. Im not concerned with the Centr. Locks Codes, but I posted the entire scan none the less. Regarding the P1128 Code, I have cleaned the MAF (and changed the air filter while i was in there) but no luck. The Check Engine Light has been on steady for a lil while now and the ESP light comes on intermittently (its on more than its off). Thanks in advance for your help!

replace the acceleration sensor, I think that fixes the ESP issue, and I don't think its expensive, someone else will have to add to that.

I had the internal memory module failure on my haldex, replaced the haldex controller with the 'blue controller'. this unfortunately isn't cheap. Got mine on sale, $750, but on the upside, the car handles a little better accelerating thru turns.

Engine codes I'm not sure on...

Lock codes, total bullshit. You'll get stuff like that anytime the alarm is set off. Lock the doors with the windows down, and walk to close to the car, and you'll end up with those codes.

Brake light switch is under your dash, they get dirty and quit working, most times you can clean it and it'll fix it.

 

search for my thread on ESP fix on the forum its around 140 bucks for the sensor from worldimpex.com and is very easy to replace. located under the steering wheel column

 

thanks for the quick replies. i also forgot to add that i cleaned the fuel injectors, incase anyone has anything to add about the engine codes. ill get on the lateral accel. sensor right away if thats gonna take one more light off my dash :-) As for the AWD, are we saying that the module definitely needs to be replaced?

 

Thats the only fix I see, its solid state electronics, not like you can go in and tweak something

 

got it, maybe i can get the work done under my extended warranty (fingers crossed). As for the engine codes, im thinkin MAF or O2 sensors - does anyone know if the MAF recall extends to second owners?

 

jshil, check for airleaks in the vacuum lines and intake tubes. If you're getting hesitation or rough idle then it wouldcoincide withthe lean code.
to check the maf just disconnect it and see if the car runs better. if so then bad maf, if runsthe same then maf is fine.
the second code maybe the secondary air pump, but just a guess though. Maybe a leak in the hoses somewhere?

 

thanks, im gonna d/c the maf. Theres no rough idle, but I'll check if it runs any better unplugged, then ill check for leaks. I read somewhere else about removing the secondary air intake. what exactly would that do for me?

 

ok, so i d/c'd the MAF and Im thinkin, 'I hope I can tell the difference if this really is the problem'.....WOW! what a difference....so, anyone have a suggestion on the best place to pick one up or which isthe best aftermarket replacement? And another question, with my AWD having issues, is my car still gettin a close-to-normal amounts of torque to the back wheels or am i drivin a FWD til i get it fixed?

 

Iirc, it's only an 80/20 ratio to begin with. So that's 80% to the front wheels and 20% to the rearonly when it needs it. What was the difference that you noticed between unplugged and plugged?
